Hello,
I have the radxa with no mmc, I have tried booting with several distros with no luck. Tried debian buster from your website and no luck. The green light turn on but the screen remain black. Is my unit DOE or is there something I can do o something Im doing wrong. I using windos to flash the OS using balena.
Cheers,
Abel
Hi Abel,
There is no problem with your operation, we can use Etcher to flash OS on Windows. I want to know what brand of SD card you use.
Hi Setq,
Thanks for your reply. I have tried several sized and brands of sd cards, 8 and 16 gb from kingston, sandisk and samsung. None of them worked. Also tried an sd card flashed with volumio that I am running on a raspberry pi zero and got no response.
Cheers,
Abel
Can you attach a serial console and post your output? Also make sure you use the right image like what xixhaga said.
Hi,
I sadly dont have the seria console cables.
Thanks,
Abel
I have the same problem with my 1GB Zero (no EMMC) that I received today.
Iāve tried a monitor and 2 HDMI TVs but I get no output.
Iāve tried Debian, Ubuntu, and Twister all from the links on the Radxa Downloads page. I flashed the SD cards using Belena Etcher.
Iāve used 2 different SD cards (64GB and 16GB SanDisk - thatās all I have).
Green light is on (doesnāt flicker so I donāt know if anything is happening).
Not sure what else to try.
Make sure the file name contains radxa zero. Then if you can attach a serial console as mentioned above we can see what was wrong with the boot process itself.
I used these onesā¦
radxa-zero-debian-buster-xfce4-arm64-20220210-0524-mbr.img
radxa-zero-ubuntu-focal-server-arm64-20220221-0514-mbr.img
I didnāt save the Twister file after flashing but it was the right one too.
I donāt have a serial console capability. Can I put the SD card in a Linux PC and look for a log file after Iāve tried to boot it?
Image file looks alright. Make sure you wait for a while before turning it off since the first boot will take longer. Serial was needed since we need to read message before Linux is even booted so there is no other way around it.
I waited for a few minutes and the screen never even flickered and it just said there was no signal. Normally when Linux boots, it shows lots of messages on the screen so you can see whatās happening. Does the Zero not do this?
OK. I got it to boot!
I put the SD card into a Linux PC and deleted all of its partitions, then I re-flashed it using Etcher. It seems that Etcher isnāt erasing the SD card properly before flashing it. I recommend that people having boot issues manually erase their SD card before flashing.
Iāve had success with Ubuntu server and Debian, although the wifi didnāt show up in Debian. Iāll have to work on that but otherwise, Iām good to go.
@somecdnguy For Wifi:
This always worked for me in Debian + Ubuntu
Go to Terminal / or you are in terminal if you installed Ubuntu:) and follow these steps;
$ sudo su
$ nmcli r wifi on
$ nmcli dev wifi
$ nmcli dev wifi connect āwifi_nameā password āwifi_passwordā
Thanks @gnlkrmz. I saw these instructions on the Debian install wiki and they worked fine. I should have posted that I had gotten it working.
Do you happen to know what the root login is for the Debian Buster? I tried pw=ārootā but it doesnāt work. Iām trying to setup VNCserver but it seems that the user ārockā lack permissions.
Update: I just discovered that DietPi has a version for the Radxa Zero so Iām going to give it a try. There is a root login, lots of apps to choose from, and it has SSH and VNC server enabled by default so you can do headless install and use. This distro should probably be listed on the Radxa Zero downloads page.
I did not know about this. Thanks, will check it out for sure.
